IMPROVEMENT vIN HARNESS-SADDLE SEATS.

Specification forming part of Letters Patent No. 55,348, dated June 5,1866.

To all whom it may concern:

Be it known that I, O. B. NORTH, of New Haven, in the county of NewHaven and State otl Connecticut, have invented a new and usefulImprovement in Harness-Saddle Seats; and I do hereby declare thefollowing, when tak-en in connection withthe accompanying drawings andthe letters of referencemarked thereon, to bea full, clear, and exactdescription of the same, and which said drawings constitute a part ofthis specication, and represent, in-

Figure l, a top View; Fig. 2, a side view; Fig. 3, a bottom View, and inFig. 4, a central section cutting'through line x a'. Figs. 5 and 6represent the same article as heretofore constructed.

My invention relates to an improvement in the construction in that partof `a harness called the saddle-seat,77 and in such seats as have therear thrown back to give to the seat a graceful appearance; and myinvention con-v sists in the pcculiarity of the construction, whereby itis formed in one piece instead of two, as heretofore constructed, thusavoiding' an objection which exists in the common construction-that is,as it is impossible, owing to the great strain which comes upon thesaddle-seat, to firmly unite the two parts, a necessity in making afinished job, as this part of the harness is usually plated or japanned.In either case the working of the two parts soon exposespthe joint,greatly damaging the appearance of the saddle-seat.

In order to the better understanding of my invention, as well asto showits advantages over the saddle-seats as heretofore constructed, I willproceed to fully describe the same as illustrated in the accompanyingdrawings. I will irst describe the article as commonly constructed, asillustrated, Figs. 5 and 6. In either case the general appearance ofthearti cle when iinished is `the same.

A is the top, which is cast from thin metal, with a stud, B, (one ormore) projecting from its inner side toward the rear. O is the rearplate, cast with the nut D upon it, and with a hole, a, to set onto ashoulder on the stud B. These two parts are then placed together, asseen in Fig. 6, the rear edge of the top A titting to the upper edge ofthe plate C. Then the stud B is riveted firmly down upon the plate O tosecure the two parts together; or, as bysome, instead of the stud, oneor more common rivets are employed to secure the two parts together,which is still more expensive and practically not as good as thefirst-described method. Then the seat is finished by japaning, plating,or otherwise.

In securing this seat to the saddle one screw passes through the top atd, another into the nut D, on the rear plate, U, and by thus securingthe seat to the saddle the two parts A and G, by avery slightirregularstrain, are so operated upon as to more or less open the joint betweenthe two parts, the effect ot' which irregular strain is a decidedobjection to this manner of construction.

lTo overcome this objection I construct my saddle-seat in one piece bythe process fully shown and described in my application for LettersPatent for process for casting saddleseats, filed in the Patent Otliccin even date herewith, which is substantially as follows: I form thepattern as it' to cast the saddleseat solid, with a core-print upon thatwhich is to be the open side, and mold the pattern so that the coreprintwill leave its impression in the cope, and of such form that when thepattern is removed from the flask the core may be readily inserted intothe cope and there remain suspended, so that when the cope is placedover the nowel the core will enter the mold, into which mold thus formedthe metal is poured. For more particular description see thespecification in the application before referred to.

Thus I am enabled to cast the saddle-seat in one piece, as seen in Figs.1, 2, 3, and 4. The upperplate, F, is joined to the rear plate, H, bymaking a recess in the core to form the nutE, and a hole through thecore, connecting the said nut E with the plate F, as seen in Figs. 2 and4. This connection between the two plates is necessary to formsutticient strength by which to secure the seat to the saddl Thus I haveproduced a saddle-seat complete in one piece, whereby all the objectionsto the ordinary construction are fully overcome, and my seat may beiinished in the usual manner, and when thus finished is capable ofsustaining far more strain th an the other. The object in thus makingthe seat hollow is to make the article as light as possible inimprovement and shown its advantage over the common construction, what Iclaim as new and useful, and desire to secure by Letters Patent, is

A saddle-seat of the form described, east in onepieoe, substantially inthe man ner as herein fully set forth.
